I ordered a Custom ground Hyd for a 355 SB Chevy. This 355 is in a Heavy 72 Chevelle. The cam sounds good and pulls like a Freight Train up to 6500 r.p.m.'s with ease. So far we are Happy,, but track time will tell. I will use him again if its in the budget for one of my Customers.
Been running a flat tappet from him since 2006 and very pleased with performance and service. My engine builder at the time (moved out of the area or I'd still use him) claimed he's always picked up using his cams.
Have been using Mikes stuff in BBC s since his father owned the Co. in Calif.[circa 1987]. I believe that he and Harold B. are two of the best. Mikes advantage is he grinds his own cams in house. Have not had any "issues" with his products or service.
